Duplex doppler examination of native and transplant kidney dysfunction: Technique, applications, and controversies

Academic Article

Abstract

  • Multiple studies have suggested that Doppler may improve the clinical utility of the sonographic assessment of renal dysfunction by identifying the abnormal patterns of blood flow known to occur with renal disease. Unfortunately, although the resistive index is often elevated with renal disease, the poor sensitivity and specificity of this finding has limited the clinical relevance of intrarenal Doppler analysis. Resistive index (RI) measurements may sometimes be helpful for the identification of ureteral obstruction, although the RI may often be normal, particularly when obstruction is partial or acute. Discrepant findings in the literature and recent discouraging Doppler results may be a reflection of our poor understanding of both the abnormal hemodynamics that occur with renal disease and the factors that cause an abnormal RI.
